CoStudy's High School U.S. History bank holds 430 items organised into 13 chapters that follow the published blueprint. Every multiple-choice question carries a written rationale explaining why the correct answer is correct and why each distractor is tempting but wrong, and the bank includes 10 scenario-based simulations.
Each chapter follows a domain of the published exam outline. Practise one on its own:
A sample of 12 multiple-choice questions from the bank, with the full rationale shown.
Labor movement milestones include:
Answer: A — Formation of the AFL (1886) and CIO (1935), Haymarket affair (1886), Triangle Shirtwaist Fire (1911 — led to safety reforms), Wagner Act (NLRA, 1935 — collective bargaining rights), Taft-Hartley (1947), and ongoing debates about union rights, minimum wage, and workplace safety
A) Standard milestones. B/C/D) Each is incorrect.
Digital revolution (1990s+):
Answer: D — Internet, World Wide Web (Tim Berners-Lee, early 1990s), smartphones (iPhone 2007), social media (Facebook, Twitter/X, Instagram, TikTok), e-commerce, streaming, big data, AI — transformed communication, commerce, work, education, entertainment, politics; benefits and concerns (privacy, misinformation, addiction, job disruption)
D) Standard. A/B/C) Each is incorrect.
The Japanese attack on Pearl Harbor occurred on:
Answer: A — December 7, 1941
December 7, 1941 — 'a date which will live in infamy.' D-Day was June 6, 1944, and September 1, 1939 was Germany's invasion of Poland.
The Missouri Compromise (1820) attempted to maintain balance between free and slave states by:
Answer: B — Admitting Missouri as a slave state and Maine as a free state, and banning slavery north of the 36°30′ line in the Louisiana Territory
The Missouri Compromise admitted Missouri (slave) and Maine (free) and drew the 36°30′ line to bar slavery in the northern Louisiana Territory.
Mayflower Compact (1620):
Answer: A — Plymouth Pilgrims' agreement to self-govern by majority rule
A) Standard. B/C/D) Each is incorrect.
President Andrew Jackson's Indian Removal Act (1830) targeted primarily which region's Native peoples?
Answer: B — The 'Five Civilized Tribes' of the Southeast (Cherokee, Creek, Choctaw, Chickasaw, Seminole)
The Act forced the Southeast tribes onto the Trail of Tears. Plains conflicts came later (post-Civil War), Iroquois removals mostly occurred earlier, and Pacific Northwest was not yet U.S. territory.
The Wagner Act (National Labor Relations Act, 1935) is most significant because it:
Answer: B — Guaranteed workers the right to organize unions, bargain collectively, and strike, and created the National Labor Relations Board
The Wagner Act transformed labor law and helped labor union membership peak by the 1950s. Minimum wage and child-labor prohibition came in the Fair Labor Standards Act (1938).
The Harlem Renaissance (1920s):
Answer: D — African American cultural, intellectual, and artistic flowering centered in Harlem, NYC — writers (Langston Hughes, Zora Neale Hurston), musicians (Duke Ellington, Bessie Smith, Louis Armstrong), artists (Aaron Douglas); reshaped Black cultural identity and broader American culture
D) Standard. A/B/C) Each is incorrect.
The American victory at Saratoga (1777) is most significant because it:
Answer: C — Convinced France to formally ally with the Americans
C) Saratoga signaled American viability and brought French support. A) War continued until 1783. B/D) Each contradicts the historical record.
In the Dred Scott decision (1857), the Supreme Court ruled that:
Answer: A — African Americans could not be U.S. citizens and Congress could not ban slavery in the territories
Chief Justice Taney's opinion denied Black citizenship and invalidated the Missouri Compromise. B and C are the opposite of the ruling; D echoes political rhetoric but wasn't the holding.
The Dust Bowl of the 1930s was caused primarily by:
Answer: B — A combination of drought and decades of intensive plow-based farming on the southern Great Plains
Loss of native grasses combined with severe drought turned topsoil to dust. Migration of 'Okies' to California, memorialized in The Grapes of Wrath, followed.
The Harlem Renaissance of the 1920s was:
Answer: B — A flowering of African American literature, music, art, and cultural expression centered in Harlem
Langston Hughes, Zora Neale Hurston, Duke Ellington, and Louis Armstrong are among its major figures. The Renaissance reshaped American arts and shaped later civil-rights consciousness.

Yes. Every multiple-choice item carries a written rationale that states the controlling principle behind the correct answer and then addresses each wrong option in turn — why it tempts and precisely where it fails. Knowing why the plausible answer was wrong is worth more than knowing which letter was right.
It is organised into 13 chapters that follow the published exam blueprint: Pre-Columbian America and European Exploration (pre-1607); Colonial America and the Road to Revolution (1607-1763); The American Revolution and Founding (1763-1791); The Early Republic and Jacksonian Era (1789-1848); Westward Expansion, Sectionalism, and the Civil War (1820-1865); Reconstruction and the New South (1865-1877); Industrialization, Gilded Age, and Progressive Era (1877-1920); World War I and the Roaring Twenties (1914-1929); The Great Depression and the New Deal (1929-1941); World War II (1939-1945); The Cold War and Postwar America (1945-1991); Civil Rights and the Long 1960s (1954-1975); Modern America (1980-Present). The number of questions in each chapter is proportional to that domain's published weight, so working through the bank exposes you to roughly the mix the real exam uses.

Last reviewed 2026-08-22. Banks are written against the certifying body's published exam outline and re-checked when that outline changes — exams get renumbered, retired and reweighted, and a bank written to a superseded outline teaches the wrong proportions. Figures that are re-indexed annually are deliberately not asserted as rules; the questions test the governing principle instead.
